i Application filed February 1'7, 1913. Serial No. 748,800.

To all'whom it may concern 2 Be it known that I, WrnnrAM F. COLLINS, a citizen of the United States, and residing, in the city of Pasadena, county of Los An-, geles, State of I California, have invented a new and useful Improvement in Fluid- Compressors, of which the following isa specification. V

This invention relates to a fluid compressor and the principal object is to provide a compressor mechanism for actuating flush tank mechanism and other apparatus by fiuid transmission. I a

' Another object is to provide a device of the character described 'which operates through a conduit to produce motion in a may be remote from the mechanism which compressor, h t V r .It is an object to provide a simple; compress or which may be mounted on the floor and has an'actuating device projecting above the surface of the fioor'which may be engaged by the foot anddepressed to compress the fluid therein, and having means for retracting the actuating device on release thereof; a I his a further objectto provlde a device Other objects will appear hereinafter.

panying drawingsin which, the figure isa view in vertlcal section and'elevatlon of my compressor andshowing it'as mounted upon a floor.

More specifically, 1O indicates a cylindrical 7 socket having its bodyoportion projecting through an opening 11 in a floor or wall 12.

Formed uponthe one end of said socket is a flange 13 which extends outwardly and rests upon the surface of the floor. This flange is provided with counter-bores .14

through which wood-screws 15 project and engage the floor. ,In this manner the socket is securely held in position. The body portion ofthe socket is formed with a longitudinally extending bore 16 which is' closed 7 V at its lower end by a'wall'l'f. A small bore 7 cent its outer endis a collar 20 which forms- 18 is formed concentric with through the wallj17.

The bore 18 is designed to receive one end of a tubularpiston plllar 19, which pillar is 'here shown as cylindricalin section and extending at right angles to'the wall Formed integral with the pillar and 'ad aof the class describediwhich is simple in con- 7 V H struction and easily" operated.

The invention is illustrated in the accom- .be operated by the compressor,

The attached end of the pillar 19 is formed with a shoul der 26which rests-upon'the inner face ofthe wall 17 and isheld thereagainst by a nut 27' engaging threads 28 onthe lower end of; the V 7 pillar. These threads also serve as a mountingvfor a pipe u'nion 29gadapted to unite the lowersen'd of the pillar 19 with a conduit 30, said" conduit leading into the bore 31 I which extends the, full length of the pillar and"aflords a passage 'for' fluid; from the- ;into the conduit, thus allowing:

The thickness. ofthezwalls 32015 the cylinder: are: of the proper width to snugly fill the space: formed between the inner diameter of the bore'16 and the outer diameter of the cup washers 22. It will thus be seen that when the plunger cylinder is pressed downwardly, fluid therein will be compressed in the, chamber 34 formed above o the piston, and forced through the pillar and conduit to actuate fluid pressure 'oper- ,ated devices.

A spring '35 is provided to draw the cylinder back into its normal "posiltion, this position being limited by a set screw'36 which engages :thewall of the cyl inder near its lower end and which is adaptthe bore 16 and ed'to move vertically in a slot 37 formed along one side of thelower portion, of the L f flange 13.

Attention is directed to the V V fact that in many mechanisms with which my compressor might be used it is not essential that'the fluid forced from the chamber 34L be lostrbut that when the cylinder is released the spring 35 will draw it back through the conduit and relieve the pressure which existsbetween thecompressor and the actuated mechanism. In so doing the com-' pressor will be fitted for causing another impulse within the conduit.

What I claim is:

1. A compressor comprising a socket, a pillar rigidly mounted on the bottom of said socket, said pillar being formed with a bore, a piston rigidly 'mounted on said 7 pillar, a cylinder open at its lower end and V 7 closed atits upper end reciprocally m0unt5 "ed in the socket with its outer periphery slidably contacting the inner periphery of the socket and its inner periphery slidably contacting the piston, and a spring inter posed between the piston and the upper end of the cylinderfor normally maintaining the latter in its uppermost position.

2. A compressor of the character depipe connection on 'the lower end of said pillar, a piston head rigidly mounted on 7 said pillar, a reciprocal cylinder having its cylindrical walls interposed" between the piston head and the walls of the socket,

said reciprocal cylinder closed at-its upper end forming a chamber above the piston piston and the top most positon.

3. A compressor of the character described, comprising a cylindrical socket, a

tubular pillar supported in said socket, a

'pipe connection on the lower end of said pillar, a piston head rigidly mounted on said pillar, a" cylinder having its cylindrical walls interposed between the piston and the -walls of the socket, said cylinder closed at its upper end forming a chamber above the piston communicating with the bore in the pillar, and a spring interposed between the of thecylinder to maintain the latter in its uppermost position, and means for holding the cylinder against rotation including a stud connected to the wall thereof extending through a vertical slot in the walls of the socket. I

4. A compressor of the character described, comprising a socket, a piston rigidly secured within said socket, a hollow plunger open at its inner end, said plunger sliding in the socket and containing the piston, spring means forholding the plunger normally in its elevated position, and means extending through said piston and socket to connect the chamber formed in the upper V end of the plunger above the piston with the SCllbGd, ,comprlsing a cyl ndrical socket, a

tubular pillar supported in said socket, a

exterior of thesocket;

In witness th't I claim the foregoing I have hereunto subscribed my name this 11th day of Febru ary,'1913. v
